Abstract

This memo provides an overview of the GSMP (General Switch Management Protocol) and includes information relating to its deployment in a IP network in an MPLS environment. It does not discuss deployment in an ATM (Asynchronous Transfer Mode) network or in a raw ethernet configuration.

Abstract

   This memo provides an overview of the GSMP (General Switch Management

   Protocol) and includes information relating to its deployment in a IP

   network in an MPLS environment.  It does not discuss deployment in an

   ATM (Asynchronous Transfer Mode) network or in a raw ethernet

   configuration.

1. Overview

   The General Switch Management Protocol (GSMP) has been available to

   the IETF community for several years now as informational RFCs.  Both

   GSMPv1.1 (released in March 1996 as RFC 1987 [2]) and GSMPv2.0

   (released in August 1998 as RFC 2297 [3]) are available.  Several

   vendors have implemented GSMPv1.1.

   In V1.1 and V2 GSMP was intended only for use with ATM switches.

   During the course of the last two years, the GSMP working group has

   decided to expand the purview of GSMP to the point where it can be

   used to control a number of different kinds of switch and can thus

   live up to what its name indicates; a general switch management

   protocol.  To do this, commands and arguments needed to be

   generalised and sections needed to be added, discussing the manner in

   which the generalised protocol could be applied to specific kinds of

   switches and port types.  In short, the protocol has gone through

   major changes in the last 24 months.

RFC 3294                   GSMP Applicability                  June 2002

   GSMP provides an interface that can be used to separate the data

   forwarder from the routing and other control plane protocols such as

   LDP.  As such it allows service providers to move away from

   monolithic systems that bundle the control plane and the data plane

   into a single tightly coupled system - usually in a single chassis.

   Separating the control components from the forwarding components and

   using GSMP for switch management, enables service providers to create

   multi-service systems composed of various vendors equipment.  It also

   allows for a more dynamic means of adding services to their networks.

   The IETF GSMP working group was established in the routing area

   because GSMP was being seen as an optional part of the MPLS solution.

   In a MPLS system, it is possible to run the routing protocols and

   label distribution protocols on one system while passing data across

   a generic switch, e.g., an ATM switch.  GSMP provides the switch

   resource management mechanism needed in such a scenario.

   GSMP has also been selected by the Multiservice Switching Forum (MSF)

   as its protocol of choice for the Switch Control Interface identified

   in their architecture.  The MSF is an industry forum which, among its

   activities estab...
